One solution would be to find some smaller blocks!<br />

Sampling<br />
This is the whole concept of digital sampling. A digital device<br />
deals only in numbers. In order for this device to recreate a Sine<br />
wave, for example, it must use digital “blocks” much like in Figure<br />
10.25.<br />
It cannot simply draw a line and have a Sine wave. It must “draw”<br />
the shape one step (block) at a time. The width of the blocks is<br />
like a measurement of time; how often can it draw a part of the<br />
wave shape? This is called the sampling rate.<br />
The height of the blocks is governed by the power of the sampler.<br />
How accurate can each measurement be? How many bits of<br />
information may I use to measure the shape?<br />
Assuming you were lucky enough to find another pile of 300mm<br />
blocks, you can now see that the animal has far less chance of<br />
escaping. Why? Because the smaller blocks have allowed you to<br />
make a better copy of the shape of the cave entrance.<br />
Safe at last!<br />
Actually, you are safe for two reasons. One, because the blocks<br />
weren’t as wide. The other because they weren’t as high. You<br />
could have simply chosen blocks that were 300mm high by 1m<br />
wide. Or the other way around.<br />
Sampled <strong>Sound</strong>s with Bit Crash Effect<br />
This is what Bit Crash can achieve. Instead of making a perfect<br />
“drawing” of the wave shape, you can decide to use a lower<br />
sampling rate, and/or use less bits of information. Both methods<br />
will make a less accurate representation of the wave shape. A<br />
type of distorted shape will result.<br />
This can result in quite a nasty sound, so the <strong>GAIA</strong> includes a<br />
dedicated Filter in the Bit Crash effect in order to smooth out the<br />
sound.<br />
For a great example please try Preset Patch B-8, where the Bit<br />
Crash effect creates a vocal sound!<br />
